 #### op-contracts/v1.6.0 - Fault proof fixes
 
 The release fixes security vulnerabilities found in Fault Proof contracts. They were made in response to security vulnerabilities identified during a series of third-party security audits by Spearbit, Cantina, and Code4rena. None of the vulnerabilities have been exploited, and user assets are not and were never at risk.
